This probably isn't a similar problem, OpenBSD/{i386,amd64} do not support bigmem, so memory above 4GB physical is not detected.

There is more than just RAM mapped into physical address space, including various ROM's and the PCI configuration space.. 2/3G is the max that will be detected as of now, OpenBSD obtains a memory map from the BIOS.

You can check your BIOS settings for anything that might reclaim some of the address space so it can map additional RAM, AGP apererature sizes and shared video memory are one areas of interest.

I have split your message & responses from the original thread. Even though it may be a similar subject, there are differences in the details. If discussions continued on both fronts, continuity would suffer & become confusing.

For these reasons, we discourage posters from tagging onto existing threads.
